Behold. I've recently got 79 Summoning as well, n' I feel good!

Haven't been so excited since I got the Godsword! I know that if you start to compare these titans to other familiars they aren't as amazing as it looks, but just the fact that you can summon these beasts keeps me happy.
On the more technical side, it actually didn't cost that much. Getting it from 76 to 79 cost about 5m, however, I've been stacking unswapable pouches since level 73, and now I actually have more shards than when I started, covering all my Summoning in the future. I'm broke, but I look at it as an investment!
